ok, thank you.
The transaction boundry was ok in my original code, but the first tip was the right one.
But there is another question. What about relationships like this:
| UserTransaction ut = sessionContext.getUserTransaction();
| ut.begin();
| MyEntity a = em.find(MyEntity.class, Long.valueOf(1));
| ut.commit();
|
| ut = sessionContext.getUserTransaction();
| ut.begin();
| a.setName("FOO2");
| MyRelatedBean b = a.getMyRelatedBean();
| em.merge(a);
| ut.commit();
|
Of course, that ends with a LazyInitializeException. But can I 'integrate' a bean in the transaction to use it as normal accessed (via find or Query) bean?
Greetings
Klaus
